Bike engine vs Car engine for track day use
Help,
I can’t make my mind up on what engine to install in my car. I'm in a really good position, I bought the car with the un-used Zetec engine and
a fully re-cond BHG close ratio type 9 with a long first gear (again un-used). One of my mates said the only way to go is with a bike engine as all I
only want to track this car, I bought a zx9 engine at the weekend as advertised on this forum. I suppose it's a nice dilemma, but I need some
informed help. I have had bike and car engines in 7's before, but only as road cars. it's the combination of 2l Zetec/bike carbs/and the
close ration gearbox that make me think and think.
I need to make my mind up soon, so constructive comments welcome.
Andy

Even though I've never ridden a bike or driven a BEC. For sole track use the BEC makes a lot of sense. Especially if you get a decent paddle
shift system too.

A lot comes down to cost too, if you build yourself a Zetec that will compete with a BEC (ie ~200bhp), its likely to cost more, plus I suspect the
Zetecs might want dry sumping for track work, so adding further expense if thats the case.
I know what Chris means when saying that BECs aren't suited to large open tracks, but to be fair its all relative, a 200bhp CEC isnt
significantly better than a 150bhp BEC on an open circuit, its only when you get a lot more power that you make the big gains on laptime and straight
line speed.
cheers

I'd go with all the opinions saying bec for track - unless you're planning on doing somewhere with the length of the Mulsanne straight, or
are going to spend an awful lot of dough on the zetec bike power has to be better. Just a note that if you get bored with the ZX9 motor I believe the
ZX10 & ZZR1100 are a straight swap.
I no longer run Furore Products or Furore Cars Ltd, but would still highly recommend them for Acewell dashes, projector headlights, dominator
headlights, indicators, mirrors etc, best prices in the UK! Take a look at http://www.furoreproducts.co.uk/ or find more parts on Ebay, user names
furoreltd & furoreproducts, discounts available for LCB users.
Don't forget Stainless Steel Braided brake hoses, made to your exact requirements in any of around 16 colours.

i think the zzr1100 is different fit to zx9, mikes engine certainly looks different to mine.

All,
Thanks for the considered replies, I'm going down the bec route.
It will be easier and cheaper to get it up and running as well.
Cheers,
Andy
